Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, when a waterproof material layer applied to the upper surface of a concrete flat roof deteriorates with age, instead of replacing it with a new waterproof material, the upper surface of the waterproof material is durable. The present invention relates to a mounting bracket used for fixing a channel material, which serves as a mounting base for the roofing material, on a flat roof when a method of stacking excellent roofing materials is adopted.

[0002]

2. Description of the Related Art In order to repair a flat roof with an aged waterproof material layer, conventionally, a method of peeling a waterproof material layer such as a damaged waterproof sheet and replacing it with a new waterproof sheet has been generally adopted. . Alternatively, a method has been adopted in which the effort to remove the old waterproof sheet is omitted and a new waterproof sheet is laminated on it. However, the durability of the conventional waterproof construction layer is much shorter than the life of the building, so the repair work is
I had to repeat it quite often. Also, when a new waterproof sheet is provided over the old waterproof sheet, there is a problem that both are difficult to fit together.

On the other hand, when an old slate-roofed roof in a factory or warehouse is damaged, there is no need to remove the old roofing material, and a new roofing material such as a metal corrugated sheet is placed on the roof. It has often been adopted.

Therefore, even when a concrete flat roof is used, the aged waterproof material layer is left as it is, and
By stacking roofing materials with excellent durability in the same manner as in the case of the above factories, the number of repairs for flat roofs can be greatly reduced. Alternatively, in the case of a newly built building, it is possible to use the above-mentioned roofing material as a roof lining method instead of the conventional waterproof construction as the rain proofing method for a flat roof.

However, since the flat roof made of concrete is so thick that it cannot be compared with the roofing material such as slate, the method of fixing the roofing material is confusing. However, it is also conceivable to use concrete nails or special stud bolts for embedding in existing concrete structures. However, in consideration of a typhoon, existing concrete nails and stud bolts are extremely insufficient in pull-out resistance.

[0006] Therefore, the inventor of the present application efficiently planted a stud bolt for mounting a roofing material, which is suitable for the purpose of firmly and surely planting it on an existing concrete flat roof or the like. I devised a construction method, and first, "Japanese Patent Application No. 9
Patent application as "-348026".

The outline of the prior invention is shown in FIG.
Explained by. First, bolt holes c are drilled in a thick flat roof C. Then, the pipe 11 in which the rubber bag 12 is bundled at the lower end thereof is inserted into the bolt hole c, and the reaction curable synthetic resin stock solution 13 is injected into the rubber bag 12 protruding to the back side of the flat roof C. , Drop the stud bolt E.
Then, as the resin hardens, a resin bolt head 14 for preventing the stud bolt E from being pulled out is formed at the lower end of the stud bolt E. 15 is
It is a nut for screwing onto the upper end of the pipe 11 to prevent falling.

In this way, even if the stud bolt E cannot be inserted from the ceiling below the flat roof C, the stud bolt E is quickly and firmly planted from the upper side of the flat roof C. You can

After that, a channel material B serving as a mounting base for a roofing material (not shown) is inserted into a stud bolt E by means of a substantially L-shaped press fitting 16 and a nut 17, and a predetermined position on the upper surface of the flat roof C. Fixed to.

[0010]

However, according to the construction method of the above-mentioned prior invention, as shown in FIG. 7, the bolt E, on the top surface of the channel material B serving as the mounting base of the roofing material,
The nut 17 and the press fitting 16 are in a protruding state. Therefore, as can be understood from FIG. 4 as an embodiment diagram of the present invention, these protrusions hinder the work of attaching the mounting member (tight frame) F of the roofing material to the upper surface of the channel material B. become.

The upper surface of the flat roof is flat as the entire roof surface, but has a certain degree of unevenness when viewed locally.
On the other hand, the above-mentioned invention of the prior application does not provide sufficient measures to easily attach the channel material B horizontally. Furthermore, if it rains during the roofing work, measures against leakage of water from the bolt holes will be a major problem because the location is the roof of an existing building.

[0012] Therefore, an object of the present invention is to provide a roofing material, such as corrugated sheet, which is overlaid on the flat roof through the channel material when the waterproof material layer on the upper surface of the concrete flat roof deteriorates with age. It is an object of the present invention to provide a channel material mounting structure that can easily solve these problems when adopted and can perform roofing work as quickly and reliably as possible.

[0013]

Means for Solving the Problems In order to achieve the above object, a fitting for mounting a channel material on a flat roof or the like according to the present invention comprises a corrugated plate on a mounting board such as a flat roof whose waterproof material layer has deteriorated over time. A roofing material such as the above is used for a construction method such as mounting via a channel material, and has a receiving groove portion 1 into which a channel material B is fitted by forming a shape like a metal strip bent upward. , A bolt 2 having a rectangular tube-shaped leg portion 2 which is integrally provided on the bottom surface 1a, and the receiving groove portion 1 allows the mounting stud bolt E planted on the mounting base C to pass through the bottom surface 1a. A hole 3 is provided, and both side walls 1b and 1b are
A plurality of sets of insertion holes 7, 7 for erection of the metal wire K supporting the channel material B are provided at different height positions, and when the mounting base C has irregularities, this The channel material B whose curved state has been corrected is welded and fixed to the receiving groove portion 1 by appropriately selecting the erection height position of the metal wire rod K with respect to the mounting brackets arranged at the points. And Then, the mounting bracket is made by bending a single metal plate cut into a predetermined shape.

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to FIGS. The present invention and the prior invention, the above-mentioned "Japanese Patent Application No. 9-348026"
The main difference with the conventional pressing metal fitting 1 shown in FIG.
6 in place of the mounting bracket A shown in FIGS.

In FIG. 4, a corrugated plate-like roofing material D is mounted on a flat roof (mounting base) C made of reinforced concrete whose waterproof material layer has deteriorated with the use of this mounting bracket A, and its mounting base (frame material). ) Is shown as a partial vertical cross-sectional view of the state in which the material is thatched through the channel material B.

Reference numeral E in FIG. 4 denotes a stud bolt which is planted on the upper surface of the flat roof C by the construction method of the prior invention.
F is a support fitting (tight frame) that is fixed on the channel material B and directly supports the roofing material D, and has a form in which a metal strip is bent according to the corrugated shape of the roofing material D. There is. Further, H is a wooden timber which is arranged in parallel on the flat roof C at a predetermined interval and reliably supports and supports the load of the roof. Then, an insulating space is formed on the upper side of the flat roof C.

FIG. 5 is a vertical sectional view taken along the line YY of FIG. The construction method for planting the stud bolts E on the flat roof C has already been described in the section "Prior Art", and therefore will be omitted here.

The mounting bracket A is formed into a three-dimensional shape shown in FIG. 1 by bending a single metal plate (not shown) cut into a predetermined shape. That is, as shown in FIG. 5, an upward U-shaped receiving groove portion 1 for completely fitting the channel material B with the opening b thereof facing downward,
The bottom of the bottom surface 1a is provided with a square tube-shaped leg portion 2 which is integrally provided.

A long bolt hole 3 through which the stud bolt E is inserted is provided on the bottom surface 1a. Further, a plurality of sets of vertically elongated slits (insertion holes) 7, 7 are provided on the opposite side walls 1b, 1b of the receiving groove portion 1 facing each other at different height positions. In this case, the side wall 1b is provided at three places near one side end and two places near the other side end, for a total of five places.

Each set of vertically elongated slits 7, 7 is for loosely fitting the metal wire K in a state of straddling the side walls 1b, 1b, as shown by the phantom line in FIG. . As the metal wire K, a copper wire or the like that is relatively easy to bend may be selected.
As will be described later, this metal wire K has a channel material B
It plays a role of temporarily supporting at a predetermined height position (see FIG. 6).

As can be seen from FIG. 1, the rectangular tube-shaped leg portion 2 has opposed side faces 2a, 2a extending downward at right angles from both side ends of the bottom face 1a, and one side end of each opposed side face 2a. It is composed of opposed side surfaces 2b, 2b each extending laterally at right angles and reaching another opposed side surface 2a.

The free end of the opposing side surface 2b is projected to the outside of the adjacent opposing side surface 2a to form a protruding piece d. This protruding piece d plays a role of preventing rainwater from flowing into the inside of the leg portion 2 when it rains during construction.

Next, in order to fix the channel material B on the flat roof C using the mounting bracket A, as shown in FIG.
Stud bolts E that have been planted in place on the flat roof C
Then, the long bolt hole 3 of the bottom surface 1a of the receiving metal fitting A is inserted.
Then, if the mounting bracket A is properly positioned and the nut 4 screwed to the stud bolt E is fastened, the flat roof C
The work of fixing the mounting bracket A on top is easy and quick.

Next, a large number of wooden timbers H are placed on the flat roof.
Are arranged in parallel with each other in the direction orthogonal to the channel material B at a predetermined distance. After that, channel material B,
It is dropped into the receiving groove portion 1 of each mounting bracket A and supported.

At this time, if the flat roof C has a locally recessed portion, the lower surface of the channel material B reaches the bottom surface 1a of the receiving groove portion 1 at that portion, as shown by a virtual line in FIG. Channel material B that does not fall and is in a floating state
Is kept horizontal.

However, in the case where the mounting bracket A and the wooden timber H are arranged at a wide interval, or depending on the type of the channel material B, the channel material B falls to the bottom surface 1a due to its own weight and bends downward. There is also. In such a case, the metal wire K is used to prevent this drop.

That is, as shown in FIG. 6, among the five sets of vertically oriented slits 7, 7 provided in the receiving groove portion 1, the channel material B is located at a position slightly higher than a position where the channel material B can be supported in a substantially horizontal direction. A set of vertical slits 7, 7 is selected, and a metal wire K is installed between these slits. Then, the channel material B dropped in the receiving groove portion 1 is temporarily supported by the metal wire material K.

After that, if a pressing force is exerted by stepping on the channel material B with a foot or the like, the metal wire rod K made of copper is dented relatively easily (not shown), so that it is lifted to some extent. The channel material B can be brought to a correct horizontal state.

Therefore, the channel material B, which is housed in the receiving groove portion 1 and temporarily fixed by the metal wire K, is shown in FIG.
As shown in Fig. 2, if the side wall 1b is welded, the work of firmly fixing the channel material B to the predetermined position in a straight state without slack even on the uneven roof C can be completed quickly and surely. Can be done. The symbol G indicates a welded portion. The stud bolt E is not shown in FIG.

Similarly, a large number of channel materials B are
They are arranged in parallel at a predetermined interval from each other and are arranged orthogonally on the wooden block H group. After that, the method of roofing the roofing material D on the group of channel materials B is not different from the well-known conventional method.

That is, first, as shown in FIG. 4, the tight frame F of the roofing material D is welded and fixed over the entire length of the upper surface of each channel material B. At the time of this attachment work, unlike the construction method of the invention of the prior application shown in FIG. 7, there are no obstructive protrusions such as the stud bolt E and the pressing metal fitting 16 on the upper surface of the channel material B ( 4 and 5
reference). Therefore, the mounting work of the support fitting F can be performed accurately, quickly, and easily.

After the mounting of the support metal fittings F is completed, as shown in FIG. 4, the roofing material D is covered on the roof metal fittings D by the bolts 5 and nuts 6 protruding from the respective peaks of the support metal fittings. Then, if the mountain portions of the support metal fitting F are firmly joined to each other, the roofing work is completed.

Even if it rains during the work of mounting the channel material B and the roofing material D, the bolt holes c formed in the flat roof C are formed in the receiving groove portion 1 of the receiving metal fitting A and the rectangular tubular shape. Since it is surrounded by the leg portions 2 and the protruding piece d is provided, it is possible to almost certainly eliminate the risk of water leakage to the attic. In order to more surely eliminate the risk of water leakage, a caulking material (not shown) may be applied to the places where there is a risk.

The mounting base of the channel material B is not limited to the flat roof C, and may be, for example, a concrete wall or the like.

[0035]

As is apparent from the above description, the use of the fitting for mounting a channel material on a flat roof or the like according to the present invention provides the following excellent practical effects. (A) On the upper surface of the channel material that serves as a mounting base for the roofing material, unlike the prior art, a bolt for fixing the
The nuts and metal fittings do not protrude and are completely flat.
(B) Therefore, the work of attaching the tight frame to the upper surface of the channel material can be performed quickly and accurately. (C) Before welding the channel material to the receiving groove,
Since it can be moved up and down in the groove, even if there is local unevenness on the upper surface of the flat roof, the work of mounting in a straight state without sagging can be performed extremely easily and quickly. (D) To temporarily fix this straight state when the channel material is welded and fixed to the receiving groove portion, simply select one of the plurality of insertion holes and insert the metal wire. Is enough. (E) Since the bolt hole provided on the flat roof is surrounded by the receiving groove portion of the receiving metal fitting and the rectangular tube-shaped leg portion, even if it rains during the construction, there is no need to worry about the rain. (F) The mounting bracket can be efficiently mass-produced from a single metal plate.
